The invention relates to a sedimentary facies identification method, device and system, and belongs to the technical field of oil-gas field development geology. The identification method comprises the following steps: carrying out ancient landform recovery on a research area to obtain an ancient landform map after deposition of the research area; converting the ancient landform map into a vector structure map; selecting a calculation section on the vector structure map along the object source direction; selecting a plurality of deposition points on the calculation profile, including the highest deposition point; obtaining gradient and horizontal displacement of each deposition point relative to the highest deposition point according to the coordinates of each deposition point; performing staged fitting on the gradient and the horizontal displacement of each deposition point relative to the highest deposition point, finding out inflection points between stages, and taking a gradient value at the inflection poi
